Question

if the thickness of a pile of 12 cardboards sheet is 45mm then find the thickness of 240 sheets in centimeters.

Answer 1

Thickness of 12 cardboards = 45mm
As we know that, 1 cm = 10 mm

Therefore,

Thickness of 12 cardboards = 45/10 cm = 4.5 cm

Now,

Thickness of 1 cardboard = (4.5/12) cm =0.375 cm

Again,

Thickness of such 240 sheets = (240 x 0.375) cm

=> Thickness = 90 cm
